After reading your Stinchcombe News this morning I have a thought for you.
Did you watch the program on Sunday Channel 5 – How to deep clean your home. To be repeated Thursday at 10 p.m.? It was so helpful to find out about the germs in one’s home and how to avoid problems.
It was really illuminating and you will never look at your tv controller in the same light again.
